Paratalainga distanti (Jacobi, 1902) is a cicada found in Vietnam, Thailand… and likely adjacent nations. One thing that makes this cicada unique, as well as other members of the tribe Talaingini, is the large number of cells that compose its forewings (tegmina with the nervuration densely reticulate).

Name, Location and Description
From Davis’ key to Okanagana1:
A. Male uncus not hooked at the extremity, sometimes sinuate.
B. Expanse of fore wings more than 50 mm.
C. Base of fore and hind wings orange-red more or less variegated with black.
DD. The outer edge of the front wing of a more continuous curve. Medium-sized species, except schaefferi, which is large.
EE. Legs, especially the front pair considerably blackened.
FF. Dull-bodied species or at most feebly shining, with proportionately narrower wings, and the hind margin of pronotum orange or reddish, except in tristis where it is black. Dorsum of the abdomen often with conspicuous transverse rows of short silvery hairs.
Venation about as in canadensis, but the veins not thickened. Pronotum generally all black, but sometimes mottled with dull red on each side of the center. Further distinguished from the other two species in this section by having the abdomen beneath centrally pale. Expands about 70 mm
